It took almost a month for officers to admit drugs paraphernalia was found at the 25-year-old model’s £1million country home in Wrotham, Kent.

And it was not until Wednesday’s inquest, which confirmed the death was caused by heroin, that it emerged her 11-month-old son Phaedra was in the house with her body for 17 hours.

“Parents on website mumsnet branded Peaches a hypocrite for giving advice about being an “Earth mother” while a heroin addict”

It is believed that Kent Police said Peaches’ death was a mystery to protect her rock musician husband Tom Cohen, 23.

A spokesman said yesterday: “We had a duty of care to Miss Geldof’s family and it would be irresponsible to prematurely release details which may have led to further speculation without having established full circumstances.”

Meanwhile, parents on website mumsnet branded Peaches a hypocrite for giving advice about being an “Earth mother” while a heroin addict.

But TV presenter Piers Morgan, 49, tweeted: “So much viciousness to Peaches” and blamed her mum Paula ­Yates, who died from heroin in 2000 aged 41.
